Abstract: An operator of a digital audio workstation (DAW) application is able to assign individual tracks of a DAW session for export to specific players within a musical score of a scorewriter application. The DAW operator associates each track with a player identifier, which is retained in association with an interoperable format file generated by the export process. When the scorewriter imports such a file, it extracts the player identifier and uses it to map the track to a scored instrument. The mapping may also depend on a scorewriter arrangement of players for the instruments. The DAW operator may assign multiple tracks representing a given instrument played with different techniques to a single instrument part in a score. The playing techniques for the instruments are also associated with the tracks and may be parsed by the scorewriter to annotate the score with the corresponding notations.

Abstract: Music creation applications enable users to enter new objects into a musical project using gestures mediated by input maps that are adapted to the musical context of the object entry location. The musical context may be defined by an explicit aspect of the musical project or implicitly by notes or intervals already entered into the project. The adaptation of the input maps may include spatial scaling to provide greater space to objects favored by the context. The context-adapted input maps may be displayed and used to guide user input, such as with gestures on a touch screen. In some implementations, input-sensitive regions of input maps are scaled in accordance with the musical context without being displayed. The methods apply to musical object entry via pop-up input maps and virtual instrument displays.

The light beam is non-polarized or depolarized, or, respectively, the light beam is polarized and the radio-sensitive optical fiber is a polarization-maintaining fiber.

Abstract: A method for manufacturing a treated optical fiber for a temperature sensor is provided. The method includes a) obtaining an optical fiber from pure silica or doped by one or more elements from among fluorine and nitrogen, b) imprinting, using a femtosecond laser, at least one Bragg grating in the optical fiber to obtain an imprinted fibe, the Bragg grating extending longitudinally in a portion of the imprinted fiber and being suitable for reflecting light waves propagating along the imprinted optical fiber, the laser having a power greater than or equal to 450 mW, and c) annealing at least the imprinted fiber portion to obtain the treated optical fiber.

Abstract: Methods and systems for constructing media output by combining multiple input media channels corresponding to different views of a scene. The construction involves combining channels that have different spatial ranges and/or color ranges so as to produce a constructed output having a range that is a composite of input channel spatial and/or color ranges. The constructed output is generated dynamically from available input channels in response to output requirements specifying a view defined in part by spatial and/or color parameter ranges. Available input channels are represented by a single multi-channel source object comprising a hierarchy of grouped and aligned channels, with individual media essence files at the lowest level. Input channel ranges and relationships among the ranges are specified by metadata associated with each channel. During editing, input channels may be added, removed, or changed and the range and nature of the constructed media output are updated dynamically.

Abstract: High dynamic range media sensor output is encoded using a hybrid transfer function. The hybrid transfer function conforms to existing industry standards over standard brightness level ranges, such as between black and white reference points, and uses a different function to encode captured signals having intensities below the black point and above the white point. Precision over the expanded dynamic range of captured image data is optimally preserved using a two-byte per pixel representation. The transfer function varies across the full dynamic range without clamping off below the maximum value of the expanded captured intensity range. One hybrid transfer function conforms to BT.1886 up to the white point, and uses a linearly varying encoding gamma above the white point up to 1300% IRE, producing encoded values in a 2.14 fixed point representation. The hybrid transfer function is continuous at the white point, and may also have a continuous gradient there.
